FIST-BLOW TESTER.

SPECIFICATION forming part of Letters Patent No. 600,431, dated March 8,1898.

Application filed March 20, 1897.

To cl/ZZ whom it may con/667171,:

- Be it known that I, CHARLES LEE, a subject of the Queen of GreatBritain, residing at San Antonio, in the county of Bexar and State ofTexas, have invented a new and useful Fist-Blow Tester, of which thefollowing is a specification.

This invention relates to machines for testing the force of a blowdelivered by a persons list, and has for its object to provide a simple,durable, and efcient machine embodying a striking-cushion for receivingthe impact of the blow, recording mechanism for indicating the preciseforce of the blow, and coin operated apparatus for releasing thestriking-pad preparatory to delivering the blow, the device being thusautomatic in action.

Other objects and advantages of the invention will appear in the courseof the ensuing description.

The invention consists in a fist-blow-testing machine embodying certainnovel features and details of construction and arrangement of parts, ashereinafter fully described, illustrated in the drawings, andincorporated in the claims.

In the accompanying drawings, Figure 1 is a side elevation of theimproved machine, partly in section, with the adjacent side of thecasing removed. Fig. 2 is a front elevation of the machine, showing theindicator. Fig. 3 is a plan view of the machine with the top removed.Fig. 4. is a horizontal section on 'the line a: fc of Fig. 1.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, 1 designates the inclosing case of themachine, which is substantially in the form of a rectangular box. At itsrear the case is provided with a surrounding flange 2, which isperforated at intervals to receive fasteners by means of which themachine maybe secured to a Wall or other suitable support, and at oneside the casing is provided with a hinged door 3 for giving access tothe internal mechanism. Arranged in the lower portion of the case is atubular plunger 4', which slides through the front wall of the case andalso through a guide 5 there- Serial No. 628,521. (No model.)

in. This plunger is provided, preferably at its top, with a longitudinalguiding-rib 6, which slides through a notch or slot in the guide 5 andprevents the plunger from turning. At its outer end the plunger 4 isprovided with a rigid metal plate 7 to the outer surface of which issecured a disk or block of wood S. Outside of the block 8 is arranged arubber pad 9, and outside of said pad 9 is a cushion 10, comprising asoft flexible covering 11 and a filling 12 of hair, cotton, wool, orsimilar ymaterial for cushioning the blows delivered thereto andpreventing injury to the knuckles and the hands. Intermediate its endsthe plunger 4t is provided with an internal annular flange 13, forming ashoulder for a plate or disk 14, against which is seated one end of aspiral compression-spring 15, arranged partly within the plunger andextending beyond the inner end thereof, the opposite end of said springbeing seated in a recess in a block 16, attached to the rear wall of thecasing 1.

17 designates a cross-pin which passes transversely through the plungeradjacent to the annular flange 13, the ends of said pin projectingoutside of the plunger and being provided with washers 18, of rubber oranalogous material, which serve as bumpers, the same comingin contactwith shoulders 19, at or near the front wall of the case, for limitingthe outward movement of the plunger and cushioning the same when thrustoutward by the expansive force of the spring 15.

20 designates a latch pivotally connected at one end to the block 16 orother convenient point adjacent to the rear wall of the case andprovided at its free end with a shoulder 21 for engaging the rib 6 ofthe plunger and preventing the inward movement of the latter. The latch2O also has a lip 22,which rests on the rib 6, and is further providedwith an inclined bottom edge or face 23, against which the rib 6operates in the inward movement of the plunger for elevating the latch.24 connects loosely at its lower end to the latch 20 and at its upperend to the rear end of a lever 25. This lever is fulcrumed intermediateits ends on a bracket 26, located near the top of the case, and isprovided at its forward end and in its upper surface with a cav- IOO ity27 for receiving the coins from an angular chute 28, projecting abovethe top wall of the case and secured for convenience thereto.

29 is a weighted pin arranged in the path of the rear end of the lever25 and slidingly mounted in an arm 30 on the bracket 26. As the forwardend of the lever 27 is depressed by the weight of the coin resting inthe cavity 27 the rear end of said lever strikes against the pin 29 andis stopped temporarily thereby,

the latch 2O being lifted sufficiently to movey the shoulder 2l out ofthe path of the plunger. When the plunger is thrust forcibly in- Ward bythe blow delivered thereon, the rib 6 acts against the inclined surface23 of the latch and thrusts upward on the rod 24, thereby depressing theforward end 27 of the lever 25 and precipitating the coin into asubposed receptacle 3l, arranged inside of the case.

32 designates a horizontal spindle j ournaled in the front wall of thecase and in the upper portion of the bracket 26. This spindle isarranged at one side of the coin-chute 28 and is provided near the frontof the case and inside of the same with a drum or pulley 33, having abeveled rear ange 34 and a squarefaced forward ange 35. A cord or otherflexible connection 36 is fastened at one end to said drum and is woundaround the same, and the other end of said cord passes around aguiding-pulley 37 and connects to the plunger 4 or its rib 6, as shown.The spindle 32 extends through the front wall of the case and has a handor indicating-finger fast upon it, said hand being adapted to revolve infront of a graduated dial 38 and to register the force of the blowdelivered upon the plunger.

39 is a spring-brake which bears against the periphery of the flange 35and prevents the indicating hand or finger being carried beyond theproper point by the sudden jerk on the cord or connection 36.

In operation a coin is deposited in the chute 28 and the same falls intothe cavity 27 of the lever 25, depressing the front end of the latterand elevating its rear end so as to elevate the latch 2O sufficiently toremove the same from the path of the plunger. The blow is now struckupon the plunger, and the force of said blow is received and absorbed bythe spring 15, and at the same time the latch 2O is thrust upward andthe rear end of the lever 25 lifts the pin 29, allowing the front end ofsaid'lever to descend and deposit the coin in the receptacle 3l. As theplunger is forced inward the cord 36 is drawn upon and the drum 33rotated under the resisting influence of the spring-brake 39, theindicating hand or finger being at the same time rotated to a pointcorresponding to the distance to which the plunger was thrust inward.

The machine is exceedingly simple in construction, reliable inoperation, andwill accurately register the force of a blow deliveredupon the plunger.

It will be understood that the several parts of the machine aresusceptible of changes in the form, proportion, and minor details ofconstruction, which may accordingly be resorted to Without departingfrom the spirit or sacrificing any of the advantages of this invention.

I-Iaving thus described the invention, what is claimed as new is- 1. Ina iist-blow-testing machine, a plunger, and a compression-spring forresisting the movement thereof, in combination with a metal platesecured to one end of said plunger, a Wooden block secured to saidplate, a pad of rubber forming a facing for said block, and a cushionarranged in front of said rubber pad and comprising a flexible cover anda filling of fibrous material, substantially as described.
